Description

Rethresher

The utility model relates to a kind of Rethresher that is used for threshing, belongs to agricultural machinery technological field.

The indispensable manufacturing procedure in when threshing is the crops results or results back after the crops results with maturation, need purify seed, removes chaff, so that storage.Traditional threshing operation has manual threshing, draws with livestock and grind roller threshing and mechanization threshing.Preceding two kinds of traditional threshing operations also will be removed chaff after threshing, the amount of labour is big, troublesome poeration; Though the mechanization threshing reduces labor intensity, threshing performance is limited, also needs to remove chaff etc. after the threshing.Which kind of threshing no matter above-mentioned several threshing operation belong to, and all seed thoroughly totally can not be purified, all must be through removing chaff, screening; to the also threshing once more of band shell seed that filters out, not only labour intensity is big, and production efficiency is low; and finally grain all can not be purified Gui Cang, cause waste.

The purpose of this utility model provides a kind of Rethresher, utilizes this Rethresher to carry out threshing, and not only speed is fast, the efficient height, and also threshing is thoroughly clean, improves the grain harvest rate.

For realizing that the purpose of this utility model has adopted following technical scheme.

Make a kind of Rethresher, this Rethresher contains and takes off part, separating part and lift portion again.Take off partial fixing again on frame; The air duct of separating part is fixed on the middle part of frame, and air duct links to each other with vibratory sieve, and the discharging opening of vibratory sieve is connected mutually with lifting, makes Rethresher.

Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing:

The structural representation of the embodiment that Fig. 1, the utility model are preferentially selected for use;

Fig. 2, present embodiment take off the broken section structural representation of part again;

Fig. 3, again take off the part roller cross-sectional structure schematic diagram.

In the structural representation of Fig. 1, Fig. 2, Fig. 3,1 among the figure is frame, is fixed with roller outer wall 2 on the top of frame 1, and there is feeding hopper 3 side on the upper side of roller outer wall 2; One roller 4 is arranged in the roller outer wall 2, and the rotating shaft of roller 4 is fixed on the frame 1 by bearing block 5.The drive 6 that is fixed in the rotating shaft of roller 4 is linked to each other with electromotor 8 by driving-belt 7, and electromotor 8 is fixed on the side on the lower side of frame 1.There is discharging opening 9 below of roller outer wall 2, and the outlet of discharging opening 9 is inserted into vibratory sieve 12 tops of separating part.Be fixed on roller outer wall 2 on the upper side the side feeding hopper 3, contain the roller outer wall 2 of roller 4 and be connected in the discharging opening 9 of roller outer wall 2 belows, form the part of taking off again of the present utility model.Among the figure 11 is air ducts, and air duct 11 is fixed on the middle part of frame 1, and the drive of air duct 11 is linked to each other by driving-belt and roller 4 coaxial drives.Vibratory sieve 12 bottoms are fixed together by spring 13 and frame 1.Two layers of screen cloth are arranged in the vibratory sieve 12, and upper strata screen cloth 14, lower screen 17 have gradient, and the mesh of upper screen cloth 14 is greater than the mesh of lower screen 17.On upper strata screen cloth 14 lower edges on the vibratory sieve 12 and a sidewall that vibratory sieve 12 touches mutually, be provided with out tangerine bar mouth 15.Chaff discharging port 16 is located at the both sides up and down of upper strata screen cloth 14, and on the sidewall corresponding to air duct 11, C communicates with outlet.Lower screen 17 is in the bottom of upper strata screen cloth 14, and the mesh of lower screen 17 is less than the mesh of upper strata screen cloth 14.Put out cereal mouthfuls 18 at the lower plane place of lower screen 17, put out cereal mouthfuls 18 with the feeding inlet of vertical elevator 19.Bottom at vibratory sieve 12 also is provided with out grass-seed mouth 20.Vibratory sieve 12 is linked to each other with the eccentric shaft that driven pulley 22 drives by connecting rod 21; When driven pulley 22 rotates, under the eccentric shaft effect, affect vibratory sieve 12 vibrations by connecting rod 21.Driven pulley 22 is linked to each other with the coaxial drive of roller 4 by driving-belt, and driven pulley 22 is linked to each other with the follower 23 of vertical elevator 19 by driving-belt simultaneously.Vibratory sieve 12 has constituted separating part of the present utility model with air duct 11.Lift portion 19 of the present utility model is a vertical elevator, and vertical elevator 19 is existing lifting means.On roller 4, have and take off cutter 10 again, take off cutter 10 helical forms again and be fixed on the roller 4.Breech face at roller 4 also is fixed with stirring jaw 24.Discharging opening 9 of the present utility model is the dovetail shaped discharging opening, and some tilting parallel ribs are arranged on the discharging bottom surface of dovetail shaped discharging opening, evenly flows out so that take off thing again.

With power connection, electromotor 8 begins to rotate, and makes roller 4, air duct 11, vertical elevator 19 work simultaneously by driving-belt.To be poured in the feeding hopper 3 this moment by the shelling thing, entered in the roller outer wall 2 from feeding hopper 3 by the shelling thing, under the high speed rotating effect of roller 4, make cereal and cereal, cereal and roller outer wall 2, cereal and roller 4 and be fixed on answering of roller 4 tops and take off cutter 10 and rub to reach shelling.Grain seed after the shelling and cavings take off again in helical form under the effect of cutter 10 and move to discharging opening 9 places, and the promotion by the stirring jaw 24 of rotation is thrown into discharging opening 9 rapidly, and the rib bottom surface by dovetail shaped discharging opening 9 evenly enters in the vibratory sieve 12.The wind of air duct 11 is also sent into vibratory sieve 12, and the mixture that enters vibratory sieve 12 is carried out selection by winnowing, and lighter cavings is sent from chaff discharging port 16 by wind, delivers to the outside by outlet C again; Heavier tangerine bar overflows to vibratory sieve 12 outsides from going out tangerine bar mouth 15 under vibratory sieve 12 vibration effects; The grain seed leaks down to lower screen 17 from the mesh of upper strata screen cloth 14, after little grass-seed is leaked down from the fine mesh of lower screen 17, flows out from going out grass-seed mouth 20; Cereal then putting out cereal on lower screen 17 mouthfuls 18 enters vertical elevator 19, by vertical elevator 19 with the cereal sack of packing into.Thereby realized the purpose of this utility model.

The utlity model has following advantage:

1, simple in structure, easy to manufacture, cost is low, is convenient to promote.

2, once purify, the threshing performance height reduces labor intensity, and improves threshing efficiency.

The part of taking off again of the present utility model can be joined with large-scale united reaper, existing thresing machine Close use, cereal threshing performance when gathering in the crops to improve.
